Biomass

Biomass is an important ecological parameter because among other
things, it represents the quantity of energy being stored in a particular
segment of the biological community.
Measurement of biomass is used to determine the standing crop of a
population and the transfer of energy between trophic levels within an
ecosystem.
Biomass literally means "mass of living material" and can be
expressed in units of weight (grams) or units of energy (calories or
joules).
Unfortunately, the direct measurements of microbial biomass such as
by filtration and dry weight or by centrifugation are rarely applicable
to environmental samples.
